FDD-3020CK Heavy-Duty B-Rated Double Door Depository Drop Safe with Dual Key Top & S&G Dial Lock
The FDD-3020CK Double Door Depository Safe provides two-tier security and strict access partitioning for commercial cash-handling applications, convenience stores, retail operations, and restaurants. Built with two completely separate compartments, cash envelope deposits made through the top front-loading drawer drop directly into the top chamber, which is secured by a UL Listed Dual Key Lock. This requires two physical keys present to open, enforcing strict dual-custody control over cash drops.
The lower independent vault is secured by a mechanical S&G (Sargent & Greenleaf) Combination Dial Lock, providing keyless, highly reliable access for managers or authorized keyholders managing change tills and long-term storage. Engineered with 1/2" thick solid steel doors, an internal Anti-Fish Baffle, spring-loaded relockers, and drill/ballistic-resistant hardplates, the 200 lb FDD-3020CK delivers heavy-duty protection against burglary attempts and internal shrinkage.
Key Security & Engineering Features
- Dual-Tier Lock Configuration: Features dual key physical access control on the top drop compartment paired with a mechanical combination dial on the lower vault compartment.
- UL Listed Dual Key Top Lock: The top drop drawer chamber requires two separate keys to open simultaneously, preventing single-employee access to dropped cash.
- S&G Combination Dial Bottom Lock: High-security mechanical Sargent & Greenleaf dial lock protects the bottom compartment without requiring electronic batteries.
- B-Rated Heavy Steel Construction: Continuous-weld steel body equipped with dual 1/2" thick solid steel doors for commercial security enforcement.
- Anti-Fish Baffle: Internal sawtooth anti-fish teeth inside the drop chute prevent cash bags and envelopes from being fished back out through the deposit drawer.
- Internal Spring-Loaded Relocking Device: Automatically triggers an auxiliary lock mechanism to seal the bolts if physical tampering or punch attacks occur.
- Drill & Ballistic-Resistant Hardplate: Hardened steel plate protects the internal locking mechanisms and relockers from mechanical drill bits and ballistic force.
- Solid Active Locking Bolts: 1-1/4" solid steel active locking bolts provide rigid engagement across both door frames.
- Heavy-Duty Hinge-Side Dead Bar: Full-length steel dead bar locks into the frame to block door removal during prying or hinge-cutting attacks.
- Pre-Drilled Anchor Holes: Includes (4) pre-drilled floor mounting holes for permanent anchoring to concrete or wood subfloors (hardware not included).

Frequently Asked Questions
How do access controls differ between the FDD-3020CK, FDD-3020EK, and FDD-3020CC models?
All three models feature identical 30" x 20" x 20" exterior dimensions and 200 lb solid steel builds. The difference lies in lock types: the FDD-3020CK has a dual-key top door and mechanical dial bottom door; the FDD-3020EK has a dual-key top door and electronic keypad bottom door; the FDD-3020CC features mechanical combination dials on both doors.
How does the dual-key top door work on the FDD-3020CK safe?
The top door features a UL Listed Dual Key Lock that requires two distinct physical keys inserted and turned simultaneously. This setup prevents a single employee from accessing deposited funds without a manager or second keyholder present.
Where do items fall when dropped into the front drawer?
Deposits inserted into the front-loading drawer drop directly into the upper compartment. The lower compartment is entirely sealed off from the upper drop zone and can only be opened via the S&G combination dial.
What are the interior dimensions and weight of the FDD-3020CK safe?
The FDD-3020CK weighs 200 lbs and has a total storage volume of 3.6 cubic feet. Both top and bottom interior chambers measure 8-1/4" High x 19-3/4" Wide x 17" Deep.
